Dataset name masking rules

The dataset name property supports the use of mask characters. Asterisks (*) and percent signs (%) can be used to represent qualifiers or parts of qualifiers in dataset names.

Table 1 explains the use of asterisks and percent signs in dataset name masks.

Table 1. Mask characters for dataset names
Mask Characters	Description
*	A single asterisk by itself indicates that either one qualifier or one or more characters within a qualifier can occupy that position. An asterisk can precede or follow a set of characters.
**	A double asterisk indicates that zero or more qualifiers can occupy that position. A double asterisk cannot precede or follow any characters; it must be preceded or followed by either a period or a blank.
%	A single percent sign by itself indicates that exactly one alphanumeric or national character can occupy that position.
%%	One to eight percent signs can be specified in each qualifier.
